I. du Pont de Nemours and Company, Wilmington, DeL, a corporation of Delaware Filed May 29, 1969, Ser. No. 828,875 Int. Cl. H01j 37/00; G01r 31/00 US. Cl. 250-43 2 Sheets Drawing. 16 Pages Specification A photochemical reactor wherein a source of light energy is positioned along the longitudinal axis of a closed vessel. About the light source are situated a plurality of hollow tube reaction units each comprised of one or more tube bundles positioned so that each bundle is equidistant from and parallel to the light source. The unoccupied interior portion of the closed vessel will contain a heat transfer fluid.

Each tube bundle consists of a plurality of concentric sleeves, each sleeve being made up of interwoven hollow tubes which are spiralled about the longitudinal axis of such sleeve. The lateral portions of the tube ends of each unit are surrounded by integral tube sheets with the ends of each tube protruding at least to the outer face of said sheets and being in open communication with reducing couplers defining a headspace adjacent to said outer face. An inlet conduit and an outlet conduit extend through the wall of the vessel, the inlet conduit communicating with the reducing coupler at one end of the unit and the outlet conduit communicating with the coupler at the other end, said conduits having joining means at their other ends exterior to the vessel.
